Astronomers at Arizona State University have found an exceptionally distant galaxy, ranked among the top 10 most distant objects currently known in space. Light from the recently detected galaxy left the object about 800 million years after the beginning of the universe, when the universe was in its infancy.
Patients with gout who consumed high levels of purine-rich foods — including meats, organ meats, seafood, lentils, spinach, mushrooms, yeast, and beer — over a 2-day period increased their risk of flare almost five-fold, a case-crossover study showed.
